Features The super large LCD screen with bright backlight makes it easier to read data, and the sampling speed is fast, up to 2.5 times per second. Its photometric probe is adopted, the measurement is more accurate, the response speed is faster, the buttons are humanized, and the use is more convenient. Small in size, light in weight, it can be carried with you, does not take up space, and the measurement is simple and convenient. UV radiometer has functions such as data retention, overload display, compass, low voltage display and automatic shutdown. It is suitable for physical optics test, window insulation effect test, weather station, agriculture, sunlight radiation intensity.
